Abstract

This invention concerns an injection moulding process for soles in expansible and cross-linking "EVA" based compounds characterised in that during the cooling stage of the moulded sole (1) the spontaneous shrinkage of the same is arrested by means of a template (3) placed on the sole (1) so that the series of perimeter pin elements (3a) on the bottom surface of the template (3) couple with a corresponding series of perimeter holes (2) on the upper surface of the sole (1) whose dimensions reduce no further either during the remaining cooling phase or after cooling.
